Abstract (en)

A video coding method and apparatus realize that a calculation amount required to perform a converting process operation of compression formats can be reduced, and also deterioration in an image quality, which is caused by this compression format converting process operation, can be reduced. A video converting unit includes added information processing means for using added information contained in an input bit stream in coding operation. This added information involves a motion vector, a motion prediction difference signal, a quadrature converting coefficient, and a quantizing value. <IMAGE>
